IMPROVEMENT 1N Loolvis.

Specification forming part of Letters Patent No. 57,717, dated September 4, .1866.

To all whom it Imay concern:

Be it known that I, IsAAc N. Bonson, of Mount Pleasant, in the county of Henry and State of Iowa, haveinvented a new and useful Improvement in Looms; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specica'tion, in which- Figure l represents a longitudinal vertical section of this invention, the line aux, Fig. 2, indicating the plane of section. Fig. 2 is a plan or top view of the same. Fig. 3 is a transverse vertical section ofthe same. Figs. 4-11 are details, which will be referred to as the description progresses.

Similar letters of reference indicate like parts.

vwhich is provid ed with double, triple, or multifarious cranks intended to impart the required rising-and-falling motion to the heddleframes iu such a manner that two or more heddie-frames can be operated by the motion of the batte-n, and the construction of the loom is lnaterially s/impliiied.

It consists, further, in the arrangement of hinged dogs secured toa stationary standard, in combination with picker-staves or swords pivoted to the under side of the hatten in such a manner that when the hatten moves forward the swords readily pass the hinged dogs; but as the hatten recedes that one of the swords which happens to be raised is turned down suddenly on coming iu contact with one of the dogs, and the required motion is imparted to the shuttle at the proper intervals, the whole motion being dependent upon the motion of the hatten.

A represents the frame of my loom, which may be built of wood or any other suitable material. One end of this frame forms the bearings for the yarn-beam B, and the other end for the cloth-beam C, and between these two beams rise two' uprights, D, which form the guides for the heddle-frames E E.

In the drawings, two heddle-frames only are shown; but it is obvious that the number of said heddleframes may be increased to three, four, or more. Said heddle-frames are raised and depressed at the proper intervals by the action of cranks a a', which are formed by the axles c of cam-rollers F, and which catch in slots b b (see Fig. l) in the lower part ot' the heddle-frames. The axles c of the cam-rollers extend in a direction transversely to the hed- (lle-frames, and they have their bearings in suitable brackets or standards, which are rigidly attached to the frame A.

The cam-rollers F are provided each with two oblique or spiral shoulders, c, and with two straight shoulders,f, extending in a direction parallel to their axis, as shown in Fig. 6in detail, and also in other figures, and an oscillating motion is imparted to them by the action of hooks or projections g, inserted loosely in the arms h, which support the hatten G. As the batten recedes the projections g slide on the straight shoulders f, and on arriving at the ends of these shoulders next to the heddleframes said hooks drop down suiiciently within a rabbet cut in t-he inner side of the sword to catch under the oblique shoulders, so that when the batten moves rorward an oscillating motion is imparted to the cam-rollers, causing` the cranks a a to change their position and to impart the required motion to the heddle-frames. During the backward motion of the hatten the cam-rollers remain stationary, and the heddle-frames retain their position, keeping the shed open for the passage of the shuttle.

The motion of the shuttle is effected by means of swords h h, which are hinged to the under surface of the batten Gr. These swords connect by cords t t with the shuttle-blocks jj, and it' the shuttle Estrikes against one of the shuttle-blocks the sword to which it is attached is raised from a vertical to an inclined or horizontal position, as shown in Fig. 3 of the drawings, where the shuttle is represented as bearing against the block j. If the batten G is moved back the inner end of the sword h' strikes a dog, 7c', which is hinged to the side oi' a standard, Z, under the hatten, and by the action of said dog on the short end of the sword the sword is turned down suddenly in a perpendicular position, and the shuttle is driven to the opposite end of the shuttle-race, where it strikes the blockj. 'By this action the sword 7L is raised7 and as the bat-ten is moved out the inner end of said sword strikes the hinged dog 7c, which7 being yielding in this direction, allows said sword to pass. When the hatten is moved in again the shuttle rcturns to the block j', the sword 7L turns down, and the sword h' is raised. By this arrangement the motion of the shuttle, as well as that of the heddle-franies, is ina-de dependent entirely upon the motion of the batten7 and the construction of the loom is materially simplified.

What I claim asl new7 and desire to secure by Letters Patent, is
